Probing Identity-Specific Motion Signatures: A Controlled Diagnostic Study

Yingtie Lei, Fangxun Liu, Baicheng Wu +13

Identity recognition (e.g., person, animal re-identification) has traditionally relied heavily on static appearance cues. Yet motion--consistent, individual-specific dynamics--can…

Beyond Flat Labels: Level-Restricted Contrastive Learning for Hierarchical Fine-Grained Vision Classification

Zhiyuan Tao, Srikumar Sastry, Matthew J Thompson +9

Multimodal contrastive learning has enabled zero-shot visual classification by aligning images with textual categories. However, in hierarchically structured label spaces, existing…

Building Machine Learning Challenges for Anomaly Detection in Science

Elizabeth G. Campolongo, Yuan-Tang Chou, Ekaterina Govorkova +148

Scientific discoveries are often made by finding a pattern or object that was not predicted by the known rules of science. Oftentimes, these anomalous events or objects that do not…

Finer-CAM: Spotting the Difference Reveals Finer Details for Visual Explanation

Ziheng Zhang, Jianyang Gu, Arpita Chowdhury +5

Class activation map (CAM) has been widely used to highlight image regions that contribute to class predictions. Despite its simplicity and computational efficiency, CAM often stru…
